Patent-family-91473490

A heat exchanger and an air conditioning system having same, the heat exchanger including: a first manifold and a second manifold disposed at one and the same side of the heat exchanger; and multiple heat exchange tubes, each heat exchange tube including: two ends, the two ends respectively being a first end and a second end, the first end and second end being respectively connected to and in fluid communication with the first manifold and the second manifold; and multiple heat exchange parts, the multiple heat exchange parts including a first heat exchange part and a second heat exchange part, the first heat exchange part and second heat exchange part being respectively connected to and in fluid communication with the first end and the second end; in a lengthwise direction of the first manifold or second manifold, the ends of the multiple heat exchange tubes includes at least one pair of adjacently arranged first ends and/or at least one pair of adjacently arranged second ends. Heat exchange performance is thereby improved.
